The 20mm semi-automatic grenade launching Denel Neopup PAW-20 remains one of the weapons I would most love to get my hands on. Unlike the XM25 and simular airbirst grenade launcher, the Neopup is a direct fire weapon. In other words, you aim at your target and pull the trigger.
The first 1:30 minutes of this video is old material, after that it is new video footage of the Neopup being tested against doors, a truck and some brick walls.
